Iron Golem

Iron Golems are found in Minecraft as Utility Mobs that defend Villagers in NPC Villages from other mobs and attacks.

Iron Golems naturally spawn in NPC Villages where the number of adult Villagers is at least 35% of the number of doors. However, when manually creating one in a Village with Villagers, a Golem will defend regardless of that ratio. An Iron Golem will also spawn in player-made Villages. If you attack a Villager when there is an Iron Golem around, it will turn hostile toward you and any Wolves you might be travelling with. If you hit the Golem itself, it will also try to kill you.

To create an Iron Golem, place 4 blocks of Iron (requires 36 Iron Ingots) in a T-shape, standing upright. Place a Pumpkin / Jack-O-Lantern on the top of the T after creating it. For it to work the first time, the Pumpkin is usually placed last.
